Radioss

Endeavor

Hello, it is more of a general question about the Radioss. I used optistruct before, where I know the type of analysis (whether linear or non linear) I am going to perform, by the choice I make at the load steps creation. 

 

How can I tell or choose the type of analysis in the Radioss.? Could anyone please help?

 

Also, Could you give me more information on how can I create multiple load steps (as in Optistruct) in Radioss?

 

Thanks in advance!

Hi,

 

Radioss is a solver for highly non-linear problems under dynamic loadings by default.

 

The analysis type is defined through control cards, for example: implicit/explicit method, dynamic/quasistatic, 3D/plane strain/axisymmetric analysis,... 

 

In Radioss the concept of loadsteps can be applied through multiple engine files in which the 'subcases' can only be solved sequentially.
